在PHP中查看数据到另一个页面

I have a problem for display data from page to another page. This is index.php:

<?php
    include '../php/connect.php';
    $query = mysql_query("SELECT * FROM user
                          ORDER BY user.id_user DESC") or die(mysql_error());


    if(mysql_num_rows($query) == 0){    

      echo '<tr><td colspan="6">Tidak ada data!</td></tr>';

    }else{  

      while($data = mysql_fetch_assoc($query)){ 

        echo '<tr>';
          echo '<td>'.$data['id_user'].'</td>';
          echo '<td>'.$data['name'].'</td>';    
          echo '<td>'.$data['email'].'</td>';
          echo '<td><a href="../bukti_bayar/' .$data['upload'].'" target="_blank">View File</a></td>';
          echo '<td><a href="confirm_pembayaran.php/'.$data['id_user'].'">Konfirmasi</a></td>';
        echo '</tr>';
        ?>
        <?php
 }}
 ?>

This is confirm_pembayaran.php

    <?php
    include '../php/connect.php';

    $query = mysql_query("SELECT * FROM user
                          WHERE id_user=$id_user") or die(mysql_error());


    if(mysql_fetch_array($query) == 0){ 

      echo '<tr><td colspan="6">Tidak ada data!</td></tr>';

    }else{  

      while($data = mysql_fetch_assoc($query)){ 

        echo '<tr>';
          echo '<td>'.$data['id_user'].'</td>';
          echo '<td>'.$data['name'].'</td>';    
          echo '<td>'.$data['email'].'</td>';
        echo '</tr>';
        ?>
        <?php
 }}
 ?>

The problem is in confirm_pembayaran.php for id_user that i was click from index.php not display in confirm_pembayaran.php. What should i do for confirm_pembayaran.php?

On the index page change the link to something like this ( unless you have set your .htaccess file up to accept links as they were generated )

You should, however, not be using the mysql_ family of functions as they have been deprecated. The code, as it is now is vulnerable to sql injection - I merely posted this to show how to pass the user_id parameter from one page to another which was what ( I think ) you wanted

/* index.php */
<a href="confirm_pembayaran.php?user_id='.$data['id_user'].'">Konfirmasi</a>


/* confirm_pembayaran.php */
$user_id=isset( $_GET['user_id'] ) ? filter_input( INPUT_GET,'user_id', FILTER_SANITIZE_STRING ) : false;
$query = mysql_query("SELECT * FROM user
                          WHERE id_user='{$user_id}'") or die(mysql_error());

First you need to pass your user id in query string correctly like below:

index.php

Changes this line

echo '<td><a href="confirm_pembayaran.php/'.$data['id_user'].'">Konfirmasi</a></td>';

To

echo '<td><a href="confirm_pembayaran.php?id_user='.$data['id_user'].'">Konfirmasi</a></td>';

Then you need to change confirm_pembayaran.php

<?php
    include '../php/connect.php';
    $id_user = $_GET['id_user']; // Add this line for get your user id

    $query = mysql_query("SELECT * FROM user
                          WHERE id_user=$id_user") or die(mysql_error());


    if(mysql_fetch_array($query) == 0){ 

      echo '<tr><td colspan="6">Tidak ada data!</td></tr>';

    }else{  

      while($data = mysql_fetch_assoc($query)){ 

        echo '<tr>';
          echo '<td>'.$data['id_user'].'</td>';
          echo '<td>'.$data['name'].'</td>';    
          echo '<td>'.$data['email'].'</td>';
        echo '</tr>';
        ?>
        <?php
 }}
 ?>

Simplest way is: In index.php

<a href="confirm_pembayaran.php?userId='.$data['id_user'].'">Konfirmasi</a>

in confirm_pembayaran.php

$id_user = intval($_GET['userId']);
